Realtime HiRAS Data (Yesterday’s Solar Radio Observations)

X-Rays plot:

The OVATION Prime Real-Time (OPRT) tool is a real-time forecast and nowcast model of auroral power and is a prototype implementation of the work by Newell et al (2009). OPRT is run every 5 minutes and the web display automatically refreshes. The model output below represents hemispheric power in Geomagnetic coordinates, oriented with local noon at the top. Thus, the top half of each polar plot represents magnetic longitudes in daylight and the bottom half represents longitudes in darkness.

Total Solar Irradiance (TSI)

34 years – Instrument offsets are unresolved calibration differences, much of which are due to internal instrument scatter (see Kopp & Lean 2011).
